"According to the post office, starting March 15 the paperwork has to be submitted electronically".
This is a misinterpretation of a notice from the DMMAdvisory, which states:
As you can see, that does NOT mean paperwork has to be submitted electronically!Starting March 15, 2010, when a customer brings in a hard copy postage statement with a mailing to an acceptance site that is equipped with PostalOne!, the Postal Service™ will no longer fill out the USPS® section of the form nor round-stamp the document. To obtain a receipt, mailers are encouraged to visit the Business Customer Gateway to access PostalOne!®, the system of record.

If you want to submit paperwork electronically, you can do this with the Mail.dat module.
